CAS 13138-25-5: (2-Butenyl)triphenylphosphonium chloride

Description: (2-Butenyl)triphenylphosphonium chloride is an organophosphorus compound characterized by its triphenylphosphonium cation and a butenyl group. It typically appears as a white to off-white solid and is soluble in polar organic solvents. The compound features a positively charged phosphorus atom bonded to three phenyl groups and a butenyl group, which contributes to its reactivity and utility in organic synthesis. It is often used as a reagent in various chemical reactions, including those involving nucleophilic substitutions and as a precursor in the synthesis of other phosphonium salts. The presence of the butenyl group allows for further functionalization, making it valuable in synthetic organic chemistry. Additionally, (2-Butenyl)triphenylphosphonium chloride can participate in reactions such as Wittig reactions, where it serves as a phosphonium ylide precursor. Safety data should be consulted for handling, as with many organophosphorus compounds, it may pose health risks if not managed properly.
